Just be thankful that she didn't have explosive diarrhea.
The "star" of the comic is Fart-Chan. She's a character that was created by Jeph Jacques, who is best known for his slice-of-life webcomic Questionable Content. I've wanted to include Fart-Chan in a Friday 4Koma for quite some time now, but I just never got around to doing it. I felt the 200th installment of Friday 4Koma would be a perfect time to remedy that.
